Warning Letter 320-24-30
April 3, 2024 Dear Ms. Lee:
Your facility is registered with the United States Food and Drug Administration (FDA) as a manufacturer of over-the-counter (OTC) drug products. FDA has reviewed the records you submitted in response to our August 15, 2022 request for records and other information pursuant to section 704(a)(4) of the Federal Food, Drug, and Cosmetic Act (FD&C Act) for your facility, Jiangsu Meifan Biotechnology Co. Ltd., FEI 3017005720, at Industrial Park of Wangduo, Yazhou Town, Haian, Nantong, Jiangsu 226641, China.
This warning letter summarizes significant violations of Current Good Manufacturing Practice (CGMP) regulations for finished pharmaceuticals. See Title 21 Code of Federal Regulations, parts 210 and 211 (21 CFR, parts 210 and 211).
Because your methods, facilities, or controls for manufacturing, processing, packing, or holding of drugs as described in your response to our 704(a)(4) request do not conform to CGMP, your drug products are adulterated within the meaning of section 501(a)(2)(B) of the Federal Food, Drug, and Cosmetic Act (FD&C Act) (21 U.S.C. 351(a)(2)(B)).
Following review of records and other information provided pursuant to section 704(a)(4) of the FD&C Act, significant violations were observed including, but not limited to, the following:
1. Your firm failed to have, for each batch of drug product, appropriate laboratory determination of satisfactory conformance to final specifications for the drug product, including the identity and strength of each active ingredient, prior to release (21 CFR 211.165(a)).
Your firm manufactures OTC drug products, including antimicrobial hand wipes.1 Based on the records and information you provided, you did not demonstrate that you conduct adequate finished drug product testing on your drug products. For example, the test reports that you provided did not include an appropriate assay test for active ingredient content or impurities.
Full release testing, including strength and identity testing of the active ingredient, must be performed before drug product release and distribution. Without adequate testing, you do not have adequate scientific evidence to assure that your drug products conform to appropriate specifications before release.
2. Your firm failed to establish an adequate quality control unit with the responsibility and authority to approve or reject all components, drug product containers, closures, in-process materials, packaging materials, labeling, and drug products (21 CFR 211.22(a)).
The records and information you provided demonstrate that your quality unit (QU) did not effectively exercise its responsibilities to oversee the quality of your drug manufacturing operations.
Your QU is responsible for fully exercising its authority and responsibilities. FDA is concerned that your QU may not be conducting appropriate oversight regarding CGMP operations.

2CGMP Consultant Recommended
